Answer: After 4.55 hours the ships will be nearest to each other, and this distance would be 54.54 km.
Step-by-step explanation:
Since we have given that
Distance between ship A and ship B = 100 km
Speed at which Ship A is sailing west = 12 km/hr
Speed at which Ship B is sailing south = 10 km/hr
Since they are sailing opposite to each other, so their relative speed would be
So, Time taken is given by
Distance would be
Hence, After 4.55 hours the ships will be nearest to each other, and this distance would be 54.54 km.
Answer:
a) v = 0
b) b = 7 / 6
c) a = any number
Step-by-step explanation:
a) 7(2+5v)=3v+14
7 x 2 + 7 x 5v = 3v + 14 .... distributive
14 + 35v = 3v + 14
35v - 3v = 14 - 14
32v = 0
v = 0 ...... only v value can fit
b) -3 (3-6b)=6b+5
-9 + 18b = 6b + 5
18b - 6b = 5 + 9
12b = 14
b = 14 / 12 = 7 / 6
c) 2 (a-2)=2a-4
2a - 4 = 2a - 4
2a -4 + 4 = 2a -4 + 4
2a = 2a
a = a ........ a cab be any number
